A water halloon is being launched into the air at a 73∘ angle of elevation from the ground. The water balloon reaches a height of 30 feet directly above your head. How far from you was the water balloon launched?
Q. A water halloon is being launched into the air at a 73∘ angle of elevation from the ground. The water balloon reaches a height of 30 feet directly above your head. How far from you was the water balloon launched?
Prompt: question_prompt: How far from you was the water balloon launched?
Identify: Identify the height (opposite side) and angle of elevation to set up for a trigonometric calculation.Height = 30 feet, Angle = 73 degrees.
Use Function: Use the tangent function because we have the opposite side and need to find the adjacent side (distance from you).tan(73∘)=AdjacentOpposite.
Plug in Values: Plug in the known values and solve for the adjacent side (distance). tan(73∘)=Adjacent30.
Rearrange Equation: Rearrange the equation to solve for the Adjacent side. Adjacent=tan(73∘)30.
Calculate Distance: Calculate the distance using a calculator.Adjacent ≈3.270930 (using tan(73∘)≈3.2709).
Finish Calculation: Finish the calculation.Adjacent ≈9.17 feet.
